What to expect,going from a 10

Can anyone tell me what to expect ,i'm going from a 10" a/d/s/ rs.2 series subwoofer to a 12" a/d/s/ rs.2 subwoofer.Because they don't need a huge box,i'll moddify my old box (sealed) to house my 12.My 10 actually had a fused tensill/lead wire to the back of the cone,the cone beeing aluminum it i guess shorted out,i send out for warranty repair/replacement and they send it back looking the same,even the black spot where it shorted was still there,all they did was solder the melted tensil wire...come on a/d/s/ ...,so for a few extra money i got a brand spankin new 12" a/d/s/ rs.2.I'm powering it with a Nakamichi amplifier PA 1002,it will go in a BMW.I did like the 10" but now it will be a few days before i can experience the 12".

Thank you

I guess i'll find out...when it's in the car,i just wanna some feedback.

Thank you
